Related Party Transactions [Abstract]
Related Party Transactions	Related Party Transactions The Company is party to a Management Agreement (which may be amended from time to time), pursuant to which the Manager manages the assets, operations, and affairs of the Company, in consideration of which the Company pays the Manager management and incentive fees. Effective March 13, 2018, the Board of Directors approved a Seventh Amended and Restated Management Agreement between the Company and the Manager. The descriptions of the Base Management Fees and Incentive Fees are detailed below. Base Management Fees The Operating Partnership pays the Manager 1.50% per annum of total equity of the Operating Partnership calculated in accordance with U.S. GAAP as of the end of each fiscal quarter (before deductions for base management fees and incentive fees payable with respect to such fiscal quarter), provided that total equity is adjusted to exclude one-time events pursuant to changes in U.S. GAAP, as well as non-cash charges after discussion between the Manager and the Company's independent directors, and approval by a majority of the Company's independent directors in the case of non-cash charges. Pursuant to the Company's management agreement, if the Company invests at issuance in the equity of any collateralized debt obligation that is managed, structured, or originated by Ellington or one of its affiliates, or if the Company invests in any other investment fund or other investment for which Ellington or one of its affiliates receives management, origination, or structuring fees, then unless agreed otherwise by majority of the Company's independent directors, the base management and incentive fees payable by the Company to its Manager will be reduced by an amount equal to the applicable portion (as described in the management agreement) of any such management, origination, or structuring fees. Summary information—For the three-month periods ended June 30, 2018 and 2017, the total base management fee incurred, net of fee rebates, was $2.0 million and $2.4 million, respectively. For the six-month periods ended June 30, 2018 and 2017, the total base management fee incurred, net of fee rebates, was $4.0 million and $4.8 million, respectively. Incentive Fees The Manager is entitled to receive a quarterly incentive fee equal to the positive excess, if any, of (i) the product of (A) 25% and (B) the excess of (1) Adjusted Net Income (described below) for the Incentive Calculation Period (which means such fiscal quarter and the immediately preceding three fiscal quarters) over (2) the sum of the Hurdle Amounts (described below) for the Incentive Calculation Period, over (ii) the sum of the incentive fees already paid or payable for each fiscal quarter in the Incentive Calculation Period preceding such fiscal quarter. For purposes of calculating the incentive fee, "Adjusted Net Income" for the Incentive Calculation Period means the net increase in equity from operations of the Operating Partnership, after all base management fees but before any incentive fees for such period, and excluding any non-cash equity compensation expenses for such period, as reduced by any Loss Carryforward (as described below) as of the end of the fiscal quarter preceding the Incentive Calculation Period. For purposes of calculating the incentive fee, the "Loss Carryforward" as of the end of any fiscal quarter is calculated by determining the excess, if any, of (1) the Loss Carryforward as of the end of the immediately preceding fiscal quarter over (2) the Company's net increase in equity from operations (expressed as a positive number) or net decrease in equity from operations (expressed as a negative number) of the Operating Partnership for such fiscal quarter. As of June 30, 2018, there was no Loss Carryforward. For purposes of calculating the incentive fee, the "Hurdle Amount" means, with respect to any fiscal quarter, the product of (i) one-fourth of the greater of (A) 9% and (B) 3% plus the 10-year U.S. Treasury rate for such fiscal quarter, (ii) the sum of (A) the weighted average gross proceeds per share of all common share and OP Unit issuances since inception of the Company and up to the end of such fiscal quarter, with each issuance weighted by both the number of shares and OP Units issued in such issuance and the number of days that such issued shares and OP Units were outstanding during such fiscal quarter, using a first-in first-out basis of accounting (i.e. attributing any share and OP Unit repurchases to the earliest issuances first) and (B) the result obtained by dividing (I) retained earnings attributable to common shares and OP Units at the beginning of such fiscal quarter by (II) the average number of common shares and OP Units outstanding for each day during such fiscal quarter, (iii) the sum of the average number of common shares, LTIP Units, and OP Units outstanding for each day during such fiscal quarter. For purposes of determining the Hurdle Amount, issuances of common shares and OP Units (a) as equity incentive awards, (b) to the Manager as part of its base management fee or incentive fee and (c) to the Manager or any of its affiliates in privately negotiated transactions, are excluded from the calculation. The payment of the incentive fee will be in a combination of common shares and cash, provided that at least 10% of any quarterly payment will be made in common shares. Summary information—Total incentive fee incurred for the three- and six-month periods ended June 30, 2018 was $0.3 million. The Company did not accrue an incentive fee for the three- or six-month periods ended June 30, 2017, since on a rolling four quarter basis, the Company's income did not exceed the prescribed hurdle amount. Termination Fees The Management Agreement requires the Company to pay a termination fee to the Manager in the event of (1) the Company's termination or non-renewal of the Management Agreement without cause or (2) the Company's termination of the Management Agreement based on unsatisfactory performance by the Manager that is materially detrimental to the Company or (3) the Manager's termination of the Management Agreement upon a default by the Company in the performance of any material term of the Management Agreement. Such termination fee will be equal to the amount of three times the sum of (i) the average annual Quarterly Base Management Fee Amounts paid or payable with respect to the two 12-month periods ending on the last day of the latest fiscal quarter completed on or prior to the date of the notice of termination or non-renewal and (ii) the average annual Quarterly Incentive Fee Amounts paid or payable with respect to the two 12-month periods ending on the last day of the latest fiscal quarter completed on or prior to the date of the notice of termination or non-renewal. Expense Reimbursement Under the terms of the Management Agreement the Company is required to reimburse the Manager for operating expenses related to the Company that are incurred by the Manager, including expenses relating to legal, accounting, due diligence, other services, and all other costs and expenses. The Company's reimbursement obligation is not subject to any dollar limitation. Expenses will be reimbursed in cash within 60 days following delivery of the expense statement by the Manager; provided, however, that such reimbursement may be offset by the Manager against amounts due to the Company from the Manager. The Company will not reimburse the Manager for the salaries and other compensation of the Manager's personnel except that the Company will be responsible for expenses incurred by the Manager in employing certain dedicated or partially dedicated personnel as further described below. The Company reimburses the Manager for the allocable share of the compensation, including, without limitation, wages, salaries, and employee benefits paid or reimbursed, as approved by the Compensation Committee of the Board of Directors to certain dedicated or partially dedicated personnel who spend all or a portion of their time managing the Company's affairs, based upon the percentage of time devoted by such personnel to the Company's affairs. In their capacities as officers or personnel of the Manager or its affiliates, such personnel will devote such portion of their time to the Company's affairs as is necessary to enable the Company to operate its business. For the six-month periods ended June 30, 2018 and 2017, the Company reimbursed the Manager $3.8 million and $2.7 million, respectively, for previously incurred operating and compensation expenses. Equity Investments in Certain Mortgage Originators As of June 30, 2018, the mortgage originators in which the Company holds equity investments represent related parties. Transactions that have been entered into with these related party mortgage originators are summarized below. The Company is a party to a mortgage loan purchase and sale flow agreement, with a mortgage originator in which the Company holds an investment in common stock, whereby the Company purchases residential mortgage loans that satisfy certain specified criteria. The Company has also provided a $5.0 million line of credit to the mortgage originator. Under the terms of this line of credit, the Company has agreed to make advances to the mortgage originator solely for the purpose of funding specifically identified residential mortgage loans designated for sale to the Company. To the extent the advances are drawn by the mortgage originator, it must pay interest, at a rate of 15% per annum, on the outstanding balance of each advance from the date the advance is made until such advance is repaid in full. The mortgage originator is required to repay advances in full no later than two business days following the date the Company purchases the related residential mortgage loans from the mortgage originator. As of June 30, 2018, there were no advances outstanding. The Company has also entered into two agreements whereby it guarantees the performance of such mortgage originator under third-party master repurchase agreements. See Note 17, Commitments and Contingencies, for further information on the Company's guarantees of the third-party borrowing arrangements. Consumer, Residential, and Commercial Loan Transactions with Affiliates The Company has investments in participation certificates related to consumer loans titled in the name of a related party of Ellington. Through its participation certificates, the Company has beneficial interests in the loan cash flows, net of servicing-related fees and expenses. The total fair value of the Company's beneficial interests in the net cash flows was $18.2 million and $11.7 million as of June 30, 2018 and December 31, 2017, respectively, and is included on the Company's Consolidated Condensed Schedule of Investments in Consumer Loans and Asset-backed Securities backed by Consumer Loans. The Company purchases certain of its consumer loans through an affiliate, or the "Purchasing Entity." The Purchasing Entity has entered into purchase agreements, open-ended in duration, with third party consumer loan originators whereby it has agreed to purchase eligible consumer loans. The amount of loans purchased under these purchase agreements is dependent on, among other factors, the amount of loans originated in any given period by the selling originators. The Company and other affiliates of Ellington have entered into agreements with the Purchasing Entity whereby the Company and each of the affiliates have agreed to purchase their allocated portion (subject to monthly determination based on available capital and other factors) of the eligible loans acquired by the Purchasing Entity under each purchase agreement. Immediately after the Purchasing Entity purchases beneficial interests in the loans, the Company and other affiliates purchase such beneficial interests from the Purchasing Entity, at the same price paid by the Purchasing Entity. During the six-month period ended June 30, 2018, the Company purchased loans under these agreements with an aggregate principal balance of $93.7 million. As of June 30, 2018, the estimated remaining contingent purchase obligations of the Company under these purchase agreements was approximately $111.6 million in principal balance. The Company's beneficial interests in the consumer loans purchased through the Purchasing Entity are evidenced by participation certificates issued by trusts that hold legal title to the loans. These trusts are owned by a related party of Ellington and were established to hold such loans. Through its participation certificates, the Company participates in the cash flows of the underlying loans held by each trust. The total amount of consumer loans held in the related party trusts, for which the Company has participating interests in the net cash flows, was $168.5 million and $114.5 million as of June 30, 2018 and December 31, 2017, respectively, and is included on the Company's Consolidated Condensed Schedule of Investments in Consumer Loans and Asset-backed Securities backed by Consumer Loans. The Company has investments in participation certificates related to residential mortgage loans and REO held in a trust owned by another related party of Ellington. Through its participation certificates, the Company participates in the cash flows of the underlying loans held by such trust. The total amount of residential mortgage loans and REO held in the related party trust, for which the Company has participating interests in the net cash flows, was $294.4 million and $183.1 million as of June 30, 2018 and December 31, 2017, respectively, and is included on the Company's Consolidated Condensed Schedule of Investments in Mortgage Loans as well as Real Estate Owned. The Company is a co-investor in certain small balance commercial mortgage loans with two other investors, including an unrelated third party and an affiliate of Ellington. These loans are held in a consolidated subsidiary of the Company. As of June 30, 2018, the aggregate fair value of these loans was $20.3 million and the non-controlling interests held by the unrelated third party and the Ellington affiliate were $1.0 million and $2.7 million, respectively. As of December 31, 2017, the aggregate fair value of these loans was $27.9 million and the non-controlling interests held by the unrelated third party and the Ellington affiliate were $1.8 million and $5.3 million, respectively. The Company is also a co-investor in certain small balance commercial mortgage loans with other investors, including unrelated third parties and affiliates of Ellington. Each co-investor has an interest in a limited liability company that holds the loans. As of June 30, 2018 the Company's ownership percentage of the jointly owned limited liability company was approximately 17% and had a fair value of $1.2 million, which is included on the Company's Consolidated Condensed Schedule of Investments in Corporate Equity Investments. The Company is also a co-investor, together with other affiliates of Ellington, in the parent of an entity (the "Issuing Entity"), that holds a call right to a securitization. The Issuing Entity issued notes to the Company and its affiliates, and to an unrelated third party. As of June 30, 2018 the notes held by the Company had a fair value of $11.1 million, which are included on the Company's Consolidated Condensed Schedule of Investments in Secured Notes. Participation in Multi-Borrower Financing Facility The Company is a co-participant in an agreement with certain other entities managed by Ellington (the "Affiliated Entities") in order to facilitate the financing of certain small balance commercial mortgage loans and REO owned by the Company and the Affiliated Entities, respectively (the "SBC Assets"). In connection with the financing of the SBC Assets under a reverse repurchase agreement, each of the Company and the Affiliated Entities transferred their respective SBC Assets to a jointly owned entity (the "Jointly Owned Entity"). While the Company's SBC Assets were transferred to the Jointly Owned Entity, the Company's SBC Assets and the related debt were not derecognized for financial reporting purposes, in accordance with ASC 860-10, because the Company continued to retain the risks and rewards of ownership of its SBC Assets. As of June 30, 2018 and December 31, 2017, the Jointly Owned Entity has outstanding issued debt under the reverse repurchase agreement in the amount of $146.7 million and $106.6 million, respectively. The Company's portion of this debt as of June 30, 2018 and December 31, 2017 was $66.6 million and $56.9 million, respectively, and is included under the caption Reverse repurchase agreements on the Company's Consolidated Statement of Assets, Liabilities, and Equity. To the extent that there is a default under the reverse repurchase agreement, all of the assets of the Jointly Owned Entity, including those beneficially owned by any non-defaulting owners of the Jointly Owned Entity, could be used to satisfy the outstanding obligations under the reverse repurchase agreement. As of June 30, 2018, no party to the reverse repurchase agreement was in default. In connection with this financing as of June 30, 2018 and December 31, 2017 there was a receivable from the Jointly Owned Entity in the amount of $12 thousand and $23.4 million, respectively, which is included in Other assets on the Company's Consolidated Statement of Assets, Liabilities, and Equity. Multi-Seller Consumer Loan Securitization In December 2016, in order to facilitate the financing of the Company's share of the subordinated note held by the Acquiror, the Company entered into a repurchase agreement with the Acquiror (the "Acquiror Repurchase Agreement") whereby the Company's share of the subordinated note held by the Acquiror was transferred to the Company as collateral under the Acquiror Repurchase Agreement. The Company then re-hypothecated this collateral to a third-party lending institution pursuant to a reverse repurchase agreement (the "Reverse Agreement"). The Acquiror Repurchase Agreement is included on the Company's Consolidated Statement of Assets, Liabilities and Equity under the caption, Repurchase agreements, at fair value and on its Consolidated Condensed Schedule of Investments. The Company's obligation under the Reverse Agreement is included on its Consolidated Statement of Assets, Liabilities and Equity under the caption, Reverse repurchase agreements. As of June 30, 2018 the outstanding amounts under the Acquiror Repurchase Agreement and the Reverse Agreement were each $5.7 million and the fair value of the related collateral was $9.4 million. As of December 31, 2017 the outstanding amounts under the Acquiror Repurchase Agreement and the Reverse Agreement were each $5.7 million and the fair value of the related collateral was $9.4 million. See Note 6 for details of the Company's participation in the multi-seller consumer loan securitization. Participation in CLO Transactions As discussed in Note 6, the Company participated in three CLO securitization transactions, all managed by the CLO Manager. The CLO Manager is entitled to receive management and incentive fees in accordance with the respective management agreements between the CLO Manager and the respective CLO Issuers. In accordance with the Company's Management Agreement, the Manager rebates to the Company the portion of the management fees payable by each CLO Issuer to the CLO Manager that are allocable to the Company's participating interest in the unsecured subordinated notes issued by such CLO Issuer. For the three- and six-month periods ended June 30, 2018, the amount of such fee rebates was $0.3 million and $0.5 million. In addition, as discussed in Note 6, in the case of the CLO II Securitization and the CLO III Securitization, the Company along with certain other CLO Co-Participants made Advances to the respective CLO Issuers, to enable them to establish warehouse facilities for the purpose of acquiring the assets to be securitized. Pursuant to the terms of the warehouse facilities and the Advances, the applicable CLO Issuer is required, at the closing of each respective CLO securitization, first to repay the warehouse facility, then to repay the Advances, and then to distribute interest earned, net of any necessary reserves and/or interest expense, and the aggregate realized or unrealized gains, if any, on assets purchased into the warehouse facility. In the event that such CLO securitization fails to close, the assets held by the respective CLO Issuer would, subject to a cure period, be liquidated. As of June 30, 2018 and December 31, 2017, the Company's loan receivable related to the warehouse facility in operation at such time was in the amount of $21.0 million and $16.9 million, respectively, and is included on the Consolidated Statement of Assets, Liabilities and Equity in Other assets. Each loan receivable from these warehouse facilities is considered a Level 3 asset and its carrying value approximates fair value due to its short term nature and the adequacy of the assets acquired into the warehouse.

Related Party Transactions

The Company is party to a Management Agreement (which may be amended from time to time), pursuant to which the Manager manages the assets, operations, and affairs of the Company, in consideration of which the Company pays the Manager management and incentive fees. Effective March 13, 2018, the Board of Directors approved a Seventh Amended and Restated Management Agreement between the Company and the Manager. The descriptions of the Base Management Fees and Incentive Fees are detailed below.

Base Management Fees

The Operating Partnership pays the Manager 1.50% per annum of total equity of the Operating Partnership calculated in accordance with U.S. GAAP as of the end of each fiscal quarter (before deductions for base management fees and incentive fees payable with respect to such fiscal quarter), provided that total equity is adjusted to exclude one-time events pursuant to changes in U.S. GAAP, as well as non-cash charges after discussion between the Manager and the Company's independent directors, and approval by a majority of the Company's independent directors in the case of non-cash charges.

Pursuant to the Company's management agreement, if the Company invests at issuance in the equity of any collateralized debt obligation that is managed, structured, or originated by Ellington or one of its affiliates, or if the Company invests in any other investment fund or other investment for which Ellington or one of its affiliates receives management, origination, or structuring fees, then unless agreed otherwise by majority of the Company's independent directors, the base management and incentive fees payable by the Company to its Manager will be reduced by an amount equal to the applicable portion (as described in the management agreement) of any such management, origination, or structuring fees.

Summary information—For the three-month periods ended June 30, 2018 and 2017, the total base management fee incurred, net of fee rebates, was $2.0 million and $2.4 million, respectively. For the six-month periods ended June 30, 2018 and 2017, the total base management fee incurred, net of fee rebates, was $4.0 million and $4.8 million, respectively.

Incentive Fees

The Manager is entitled to receive a quarterly incentive fee equal to the positive excess, if any, of (i) the product of (A) 25% and (B) the excess of (1) Adjusted Net Income (described below) for the Incentive Calculation Period (which means such fiscal quarter and the immediately preceding three fiscal quarters) over (2) the sum of the Hurdle Amounts (described below) for the Incentive Calculation Period, over (ii) the sum of the incentive fees already paid or payable for each fiscal quarter in the Incentive Calculation Period preceding such fiscal quarter.

For purposes of calculating the incentive fee, "Adjusted Net Income" for the Incentive Calculation Period means the net increase in equity from operations of the Operating Partnership, after all base management fees but before any incentive fees for such period, and excluding any non-cash equity compensation expenses for such period, as reduced by any Loss Carryforward (as described below) as of the end of the fiscal quarter preceding the Incentive Calculation Period.

For purposes of calculating the incentive fee, the "Loss Carryforward" as of the end of any fiscal quarter is calculated by determining the excess, if any, of (1) the Loss Carryforward as of the end of the immediately preceding fiscal quarter over (2) the Company's net increase in equity from operations (expressed as a positive number) or net decrease in equity from operations (expressed as a negative number) of the Operating Partnership for such fiscal quarter. As of June 30, 2018, there was no Loss Carryforward.

For purposes of calculating the incentive fee, the "Hurdle Amount" means, with respect to any fiscal quarter, the product of (i) one-fourth of the greater of (A) 9% and (B) 3% plus the 10-year U.S. Treasury rate for such fiscal quarter, (ii) the sum of (A) the weighted average gross proceeds per share of all common share and OP Unit issuances since inception of the Company and up to the end of such fiscal quarter, with each issuance weighted by both the number of shares and OP Units issued in such issuance and the number of days that such issued shares and OP Units were outstanding during such fiscal quarter, using a first-in first-out basis of accounting (i.e. attributing any share and OP Unit repurchases to the earliest issuances first) and (B) the result obtained by dividing (I) retained earnings attributable to common shares and OP Units at the beginning of such fiscal quarter by (II) the average number of common shares and OP Units outstanding for each day during such fiscal quarter, (iii) the sum of the average number of common shares, LTIP Units, and OP Units outstanding for each day during such fiscal quarter. For purposes of determining the Hurdle Amount, issuances of common shares and OP Units (a) as equity incentive awards, (b) to the Manager as part of its base management fee or incentive fee and (c) to the Manager or any of its affiliates in privately negotiated transactions, are excluded from the calculation. The payment of the incentive fee will be in a combination of common shares and cash, provided that at least 10% of any quarterly payment will be made in common shares.

Summary information—Total incentive fee incurred for the three- and six-month periods ended June 30, 2018 was $0.3 million. The Company did not accrue an incentive fee for the three- or six-month periods ended June 30, 2017, since on a rolling four quarter basis, the Company's income did not exceed the prescribed hurdle amount.

Termination Fees

The Management Agreement requires the Company to pay a termination fee to the Manager in the event of (1) the Company's termination or non-renewal of the Management Agreement without cause or (2) the Company's termination of the Management Agreement based on unsatisfactory performance by the Manager that is materially detrimental to the Company or (3) the Manager's termination of the Management Agreement upon a default by the Company in the performance of any material term of the Management Agreement. Such termination fee will be equal to the amount of three times the sum of (i) the average annual Quarterly Base Management Fee Amounts paid or payable with respect to the two 12-month periods ending on the last day of the latest fiscal quarter completed on or prior to the date of the notice of termination or non-renewal and (ii) the average annual Quarterly Incentive Fee Amounts paid or payable with respect to the two 12-month periods ending on the last day of the latest fiscal quarter completed on or prior to the date of the notice of termination or non-renewal.

Expense Reimbursement

Under the terms of the Management Agreement the Company is required to reimburse the Manager for operating expenses related to the Company that are incurred by the Manager, including expenses relating to legal, accounting, due diligence, other services, and all other costs and expenses. The Company's reimbursement obligation is not subject to any dollar limitation. Expenses will be reimbursed in cash within 60 days following delivery of the expense statement by the Manager; provided, however, that such reimbursement may be offset by the Manager against amounts due to the Company from the Manager. The Company will not reimburse the Manager for the salaries and other compensation of the Manager's personnel except that the Company will be responsible for expenses incurred by the Manager in employing certain dedicated or partially dedicated personnel as further described below.

The Company reimburses the Manager for the allocable share of the compensation, including, without limitation, wages, salaries, and employee benefits paid or reimbursed, as approved by the Compensation Committee of the Board of Directors to certain dedicated or partially dedicated personnel who spend all or a portion of their time managing the Company's affairs, based upon the percentage of time devoted by such personnel to the Company's affairs. In their capacities as officers or personnel of the Manager or its affiliates, such personnel will devote such portion of their time to the Company's affairs as is necessary to enable the Company to operate its business.

In connection with the financing of the SBC Assets under a reverse repurchase agreement, each of the Company and the Affiliated Entities transferred their respective SBC Assets to a jointly owned entity (the "Jointly Owned Entity"). While the Company's SBC Assets were transferred to the Jointly Owned Entity, the Company's SBC Assets and the related debt were not derecognized for financial reporting purposes, in accordance with ASC 860-10, because the Company continued to retain the risks and rewards of ownership of its SBC Assets.

Multi-Seller Consumer Loan Securitization

In December 2016, in order to facilitate the financing of the Company's share of the subordinated note held by the Acquiror, the Company entered into a repurchase agreement with the Acquiror (the "Acquiror Repurchase Agreement") whereby the Company's share of the subordinated note held by the Acquiror was transferred to the Company as collateral under the Acquiror Repurchase Agreement. The Company then re-hypothecated this collateral to a third-party lending institution pursuant to a reverse repurchase agreement (the "Reverse Agreement"). The Acquiror Repurchase Agreement is included on the Company's Consolidated Statement of Assets, Liabilities and Equity under the caption, Repurchase agreements, at fair value and on its Consolidated Condensed Schedule of Investments. The Company's obligation under the Reverse Agreement is included on its Consolidated Statement of Assets, Liabilities and Equity under the caption, Reverse repurchase agreements. As of June 30, 2018 the outstanding amounts under the Acquiror Repurchase Agreement and the Reverse Agreement were each $5.7 million and the fair value of the related collateral was $9.4 million. As of December 31, 2017 the outstanding amounts under the Acquiror Repurchase Agreement and the Reverse Agreement were each $5.7 million and the fair value of the related collateral was $9.4 million. See Note 6 for details of the Company's participation in the multi-seller consumer loan securitization.

Participation in CLO Transactions

As discussed in Note 6, the Company participated in three CLO securitization transactions, all managed by the CLO Manager.

The CLO Manager is entitled to receive management and incentive fees in accordance with the respective management agreements between the CLO Manager and the respective CLO Issuers. In accordance with the Company's Management Agreement, the Manager rebates to the Company the portion of the management fees payable by each CLO Issuer to the CLO Manager that are allocable to the Company's participating interest in the unsecured subordinated notes issued by such CLO Issuer. For the three- and six-month periods ended June 30, 2018, the amount of such fee rebates was $0.3 million and $0.5 million.

In addition, as discussed in Note 6, in the case of the CLO II Securitization and the CLO III Securitization, the Company along with certain other CLO Co-Participants made Advances to the respective CLO Issuers, to enable them to establish warehouse facilities for the purpose of acquiring the assets to be securitized. Pursuant to the terms of the warehouse facilities and the Advances, the applicable CLO Issuer is required, at the closing of each respective CLO securitization, first to repay the warehouse facility, then to repay the Advances, and then to distribute interest earned, net of any necessary reserves and/or interest expense, and the aggregate realized or unrealized gains, if any, on assets purchased into the warehouse facility. In the event that such CLO securitization fails to close, the assets held by the respective CLO Issuer would, subject to a cure period, be liquidated. As of June 30, 2018 and December 31, 2017, the Company's loan receivable related to the warehouse facility in operation at such time was in the amount of $21.0 million and $16.9 million, respectively, and is included on the Consolidated Statement of Assets, Liabilities and Equity in Other assets. Each loan receivable from these warehouse facilities is considered a Level 3 asset and its carrying value approximates fair value due to its short term nature and the adequacy of the assets acquired into the warehouse.
